Shell tiirreted, long, and regularly tapering to a fine point, of a 

 dead bluish-white or livid-brown color ; whorls ten, rather flattened, 

 barred with eight to fifteen stout, flattened, oblique white 

 ribs, some of which are apparently double ; ribs not ter- 

 minating abruptly, but bending and flowing along the sut- 

 ural space to the preceding ones ; the intervening space 

 is marked by six or eight coarse, rounded, equidistant 

 ridges and revolving lines ; a single one, nearly as ele- 

 vated as the ribs, revolves from the upper angle of the 

 aperture ; aperture nearly round, bordered by a rib ; left 

 s. Grcfnian- lip a little cxpauded, and projecting into a perceptible an-

 twentieths of an inch ; divergence, thirty-four degrees. 



Found thrown upon Nahant Beach, and taken from fishes caught

 Nova Scotia (Willis); fossil, Beauport (Daivson). Mr. Couthouy

 superiorly, not separated from the neck by any distinct line ; tenta- 

 cula two, about an eighth of an inch long ; eyes small, black and 

 shining, at the outer base of the tentacula ; mouth rather large, 

 rounded, corrugated ; operculum horny, strong, opaque, of few 

 turns. It was sluggish in its movements, and fed eagerly upon 

 fresh ])eef, especially if somewhat macerated. 



Two imperfect shells in my possession, which I had supposed to
